MEASURING APPARATUS FOR LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 398,528, dated February 26, 1889.

Application filed October 24, 1888. Serial No. 289,027. (No model.)

T0 on whom it may concern.-

Be it known that I, CHARLEs Guivxsn Mo- LIN, of Brooklyn, Kings count-y, New York, have invented a new and useful Improvement in lileasuring Ap1 )aratus for Liquids, of which the following is a specification.

The object of my invention is to measure out liquids from bottlesas, for example, medicine or chemical reagents, which it is necessary to gage with accuracy.

My invention consists in the coinlnnat-imi of a bottle or other similar receptacle for the liquid, provided with means for ejecting said liquid, with a measuringwessel into which said liquid is received, all as hereinafter more particularly set forth.

In the accompanying drawings, Figure 1 is a vertical section of my device on the line it of Fig. 9. Fig. 2 is a plan view of said de vice.

Similar letters of reference indicate like parts.

A is a bottle or any other similarly-shaped receptacle for the liquid. ward into said bottle is a tube, 13, which is secured in any suitable way to the lower part of the throat or neck to form a downward prolongation of the same. At the upper portion of the bottle is an opening, 0, at which point is arranged an elastic bulb, D, of rubber or equivalent material. for to surround the opening C with a rim, E, for convenient application of the bulb D. In said bulb is an opening, l closed bya valve, G, which opens inward.

The throat. of the bottle is made conical to receive the similarly-formed projection H on the bottom of the 1neasuririg-receptacle I. This projection forms the conical seat of a valve, J, which is prevented from escaping into the body of receptacle I by a fixed bar, K, extending across the bottom above said seat. The receptacle I is preferably made of glass, and upon its side is inscribed a scale or scales of any suitable graduationas for drains or spoonfuls. For convenience, the

receptacle I is also provided with a handle, L, and a spout, M, from which the contents may be poured or taken into the mouth.

The operation of the device is as follows: The parts being arranged substantially as Extending down.

As shown, I preshown, on compressing the bulb D the air pressure, so increased within the botilc,forccs the liquid up the tube B and past the valve .I, which it lifts, and so into the receptacle I. As soon as the level of the liquid attains the desired point on the scale inscribed on the receptacle I, pressure is relaxed on the bulb D, which again expands, the valve G then opening. The valve J then returns to its seat. The receptacle I may then be lifted out of the bottle, the valve J being retained closed by the liquid pressure above it. The liquid is then used as desired.

It will be seen that this device affords a very convenient and accurate means ofmeas- 11 ring any liquid directly from its containing vessel without tilting the latter or in any wise pouring the liquid therefrom. It is especially useful in the iulministraiion oi medicines, especially such as require precise admeasurement, as it entirely does away with dropping or the use of such variable and erroneous measures as teaspoons or other articles of domestic use. The contents of the bottle are always protected from access of the air, and with certain solutions the device is especially advantageous, inasmuch as all shaking or disturb ance of the liquid is prevented.

I claim- 1. The combination, with thebotilc A, having a tube, B, secured to the lower portion of its throat and extending into said bottle, and a bulb, D, also communicating with the interior of said bottle, of a detachable liquid-receptacle, I, having at its bottom a tubular projection, II, constructed to tit in said throat,

and a valve, J, in said projection, substair tially as described.

2. The con'ibination, with the bottle A, having a tube, B, secured to the lower portion of its throat and extending into said bottle, and a bulb, I), having a valve, G, and communicating with the interior of said bottle, ofa detachable liquid-receptacle, I, having at its bottom a conical tubular projection, I'I, constructed to lit in said throat, and a valve, .I, in said projection, substantially as described.
